CHCH CH-CH₂ H-CI CH₂ CH CH CH₂ + CI I CH₂CH=CH-CH₂ CI II At 0°C, the following product composition is observed: product I (71%), product II (29%). At 42°C, the following product composition is observed: product I (15%), product II (85%). ANSWER THE FOLLOWING QUESTION: Why does the addition product I predominate at the lower temperature (0°C)? At lower temperature, the reaction is kinetically controlled: product I forms faster, so product I predominates. O Product I predominates at lower temperature because it has more i electron delocalization than product II. Product I is less sterically hindered, so it predominates. At lower temperature, the reaction is equilibrium controlled: product I is more stable than product II, so product I predominates. ↑

The following figure shows the energy profile of a nucleophilic substitution reaction. Potential energy :ÖH H HII.C H C-1 H HO--C---I HH Reaction coordinate H -CH HO–CHITH H + 1 According to this, it is correct to affirm: O The activation energy (4G°) shows that it is thermodynamically favorable. O Represents a reaction that occurs in one step where a pentavalent chemical species is formed. O The intermediate has lower energy than any transition state. O The formation of the intermediate releases energy and is therefore thermodynamically favourable.
